Allowe duplicate email not working

Hi,

I would need it so badly, the Allowe duplicate email plugin, but it's not working on my Joomla 3.4.1 site. There was by default installed the original duplicate email plugin, but as that one didn't work, I deinstalled that plugin and installed yours. But this also doesn't work.
What could be the reason?

Hi,
Is the plugin enabled? Do you have any other plugins or components which could be conflicting. Does it give any errors. What version of the plugin are you using, you need version 1.0.4 for joomla 3.4?
